what wire do i hook my air/fuel ratio gauge up to?
You can look for a ECU pinout at plxdevices.com, look in the support section. If all else fails, slit the wires on the O2 with a razor and check with a Ohm Meter. The signal ranges from 0-1volt. Should be around .5 at idle.
That would definetly be easier!
Separate names with a comma.
